Rockland Immunochemicals anti p75ntr mab
Steady-state distribution and delivery to the plasma membrane of PLAP and NTR-PLAP in transfected FRT cells. (A) Schemes of PLAP and NTR-PLAP (a fusion protein containing the ectodomain of <t>p75NTR</t> and the C-terminal GPI attachment signal of PLAP). (B) FRT cells stably expressing PLAP or NTR-PLAP were grown to confluence and pulsed overnight with [35S]met–cys or [35S]cys, respectively. After surface biotinylation from the apical (Ap) and basolateral (BL) domains, cells were lysed, immunoprecipitated against specific antibodies, and reprecipitated against streptavidin. (C) FRT cells were labeled for 20 min with [35S]met–cys or [35S]cys. At different times of the chase, surface proteins were biotinylated from the apical (Ap) or the basolateral (BL) side. Cells were then lysed and immunoprecipitated with antibodies against PLAP or NTR and with streptavidin beads. Samples were run on 10% SDS-PAGE and detected by fluorography. PLAP and NTR-PLAP are directly sorted to the apical surface in FRT cells, whereas a small percentage of the two proteins is delivered with similar kinetics to the basolateral domain.

Surface expression of GPI-anchored, secretory, and transmembrane proteins after FB1 treatment. (A) FRT cells stably expressing PLAP, NTR-PLAP, or gD1-DAF were grown to confluence in the absence (−) or presence (+) of FB1, as described in MATERIALS AND METHODS. After 30 min of labeling with [35S]met–cys or [35S]cys and a 2-h chase, cells were surface biotinylated from the apical (Ap) or the basolateral (BL) domain, lysed, immunoprecipitated against specific antibodies, and reprecipitated against streptavidin. (B) Amounts of labeled proteins were quantified from three independent experiments and are shown as means ± SD. Hatched bars represent apical proteins, and black bars represent basolateral proteins. Apical PLAP and NTR-PLAP, but not basolateral gD1-DAF, became unpolarized after FB1 treatment. (C) FRT cells expressing PLAP-sec, NTR-sec, p75NTR, or PLAP-PS321 were grown to confluence in the absence (−) or presence (+) of FB1, as described in MATERIALS AND METHODS. After labeling with [35S]met–cys or [35S]cys for 20 min and a chase of 2 h, apical and basolateral media were collected separately and cells were surface biotinylated from apical or basolateral domains. Polarized secretion of the secretory forms was revealed by immunoprecipitation in the apical and basolateral medium (top two panels), whereas biotinylated transmembrane proteins were revealed by double immunoprecipitation with specific antibody and streptavidin beads (bottom two panels). (D) Amounts of labeled proteins were quantified from three independent experiments and are shown as means ± SD. Hatched bars represent apical proteins, and black bars represent basolateral proteins. FB1 does not alter the sorting of transmembrane and secretory proteins.

Apical PLAP and NTR-PLAP, but not basolateral gD1-DAF, became unpolarized after FB1 treatment. (C) FRT cells expressing PLAP-sec, NTR-sec, p75NTR, or PLAP-PS321 were grown to confluence in the absence (−) or presence (+) of FB1, as described in MATERIALS AND METHODS. After labeling with [35S]met–cys or [35S]cys for 20 min and a chase of 2 h, apical and basolateral media were collected separately and cells were surface biotinylated from apical or basolateral domains. Polarized secretion of the secretory forms was revealed by immunoprecipitation in the apical and basolateral medium (top two panels), whereas biotinylated transmembrane proteins were revealed by double immunoprecipitation with specific antibody and streptavidin beads (bottom two panels). (D) Amounts of labeled proteins were quantified from three independent experiments and are shown as means ± SD. Hatched bars represent apical proteins, and black bars represent basolateral proteins. FB1 does not alter the sorting of transmembrane and secretory proteins.

Surface expression of GPI-anchored and transmembrane proteins after cholesterol depletion. (A) FRT cells expressing PLAP, NTR-PLAP, gD1-DAF, p75NTR, or PLAP-PS321 were grown on filters and treated with mevinolin (Mev.; 10 μM) for 48 h and M-β-CD (10 mM) for 60 min. Cells were then pulse labeled for 30 min, chased for 2 h, and biotinylated as usual. (B) Amounts of labeled proteins were quantified in three independent experiments and are shown as means ± SD. Hatched bars represent apical (Ap) proteins, and black bars represent basolateral (BL) proteins. Removal of cholesterol does not alter the surface expression of apical and basolateral GPI-anchored and transmembrane proteins.
